Joins in SQL
This section briefs Joins in SQL and discusses statements that fetch all the results in different tables meeting the condition.
Types of Joins in SQL
This section defines Right Join, Left Join, Inner Join, Full Outer Join, Self Join, and Cross Join. You will understand how all of these joins return values based on the input statement and conditions.

FULL Join
You will learn to return all the values in both the tables based on the input condition, regardless of their commonalities, using demonstrated examples using the FULL JOIN statement.
SELF Join
You will learn to return the values of the same table depending on the input condition given by the user using demonstrated examples using the SELF JOIN statement.
Intro to Subquery
It is also called Sub-Selects or Nested Queries. This section helps you learn to write a query within another query.
Problem Statement
A problem statement is a scenario with defined elements to be achieved at the end of the query processing. You will learn to solve and work with problem statements in this section.
What is a Subquery?
A subquery is a nested query command within another query. It is also called Sub-Selects, and it returns the value that meets the requirements of both queries. You will understand the details in this section.
How Subquery Executes?
Each subquery is executed for every row of the outer query. A correlated subquery evaluated each row processed by the parent statements. SELECT, UPDATE, and DELETE statements are the parent statements. You will understand how a subquery executes in this section.
Type of Subquery
This section discusses single-row subquery, multiple row subquery, multiple columns subquery, correlated subquery, and nested subquery to understand the subquery concept.
Demo for Subqueries
This section will help you understand each subquery with demonstrated examples.
